1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Antibiotic exposure substantially alters the production mechanisms of bacterial extracellular vesicles (BEVs), which serve as carriers for intercellular exchange of DNA, proteins, and nutrients, yet the underlying mechanisms remain elusive. Here, using Escherichia coli as a model, we uncover how antibiotic exposure enhances BEV secretion, cargo enrichment, and motility. Our results demonstrate that enrofloxacin (ENR) triggers the SOS response, leading to upregulation of the endolysin genes essd-1, rrrd, and rzod, causing peptidoglycan layer damage and promoting modest BEV formation with encapsulated bioactive components such as DNA and proteins. More critically, ENR suppresses ompR, a key regulator in the OmpR/EnvZ two-component system, downregulating the expression of the outer membrane (OM) protein OmpC and its associated Mla-OmpC lipopolysaccharide transport complex. This destabilization of the OM further facilitates BEV formation and cargo encapsulation. The ΔompR mutant in E. coli also exhibits reduced type I fimbriae and enhanced BEV motility, indicating that the OmpR/EnvZ system modulates BEV dynamics via type I fimbriae regulation. These findings reveal a novel mechanism by which E. coli adapts to sub-inhibitory antibiotic stress by modulating BEV formation and motility, with implications for biomedical nanodelivery applications.
